NGC 2841: A Spiral Galaxy
NGC 2841 is a fine spiral galaxy - a system of over 100 billion
stars, along with lots of gas, and interstellar dust. This galaxy
is somewhat similar to our own Milky Way, but is about 30 percent larger. It
is also a tighter spiral - our Milky Way has more loosely-wound spiral arms.
The darker blotches on the disk are huge clouds of interstellar dust that
obscure our view of the stars behind.
Located in the constellation Ursa Major, NGC 2841 lies about 45 million
light-years from us. It is only faintly visible through binoculars on a dark
moonless night.
The individual stars that you can see in this image are all are nearby stars
that are part of our own galaxy. With that in mind, this image provides a
kind of three dimensional effect; the stars lie in the foreground with the
galaxy hovering far in the distance.
